铜镍70/30Tube are used where high purity, resistence to bio fouling and bacteria and extreme corrosion resistance are required. They are good strength and formability. It is not difficult to weld if proper procedures and environmental precautions are used.

铜镍合金的两个主要等级为镍和70/30（70％铜和30％镍）。这些也称为溶液溶液合金。这意味着任何量的铜可溶于镍中，并且任何量的镍可溶于铜中。

When working with copper nickel alloys no pereheat and post-weld heat treatments are needed. Neither the weld or heat-affected zone are hardened by the heat of welding.
